Louis Theroux: The Settlers is a deathly warning

Louis Theroux's new film is about ultra-nationalist Israeli settlers in the West Bank .

He first visited the area in 2011 , and it's chilling that Gaza , it seems, is now again in their sights.

At his best, Theroux ’s great skill is to allow people to be themselves, unbridled.

Shuttered shops, gates and wire fences, arbitrary lines that move every day , and unseen eyes, always watching. When the two men part, Amro can’t take the short way home; a needlessly circuitous route is his only option. And again, the physical contrast with Theroux . While Amro seems to slump even as he walks, Theroux , tall and straight-backed, will soon head for coffee in Nablus a place that, for his companion, might as well be as far away as the moon.
